Answer:
Antimony - metalloid
Tungsten- Transition metal
Argon - Noble gas
Iron - Transition metal
Bromine- Halogen
Cesium- Alkali metal
Cerium- lanthanide
Uranium - Actinide
Calcium- Alkaline earth metal
Lithium - Alkaline metal
Explanation:
Lithium is an alkaline metal because it belongs to group 1 of the periodic table. This is the general name for the group.
Calcium is an alkaline earth metal as it belongs to group 2 of the periodic table. This is the general name of the group.
Uranium is an actinide as it belongs to the second series of the f block
Cerium is the second element in the lanthanide series after lanthanum
Cesium belongs to group 1 and hence is an alkaline metal.
Bromine is a halogen as it belongs to group 7 of the periodic table
Iron is a transition metal as it belongs to the first series of transition metals
Argon is s noble gas as it belongs to group 18
Tungsten is s transition element and it belongs to the third series
Antimony is a metalloid
